Description
Technical field
The present invention relates to field of video processing, particularly relate to a kind of display packing of vision signal, and a kind of display system of vision signal.
Background technology
At present, joined screen system has been applied to multiple system regions such as comprising traffic, electric power, security, by types of applications software and monitor video picture are rendered on combination, greatly facilitate the monitoring of people to Various types of data, for the fast deployment realizing data analysis and resource provides possibility.
At present, in combination Graphics Processing, the mode of many employings distributed treatment, comprise master server and display Node station, display Node station outputs to display unit display after being decoded by video compression data by the mode of software or hardware, and Techniques for Multimedia Compression common at present comprises MPEG2, H.264 etc.For H.264 compression standard popular at present, what this standard adopted is that video flowing compresses by predictive coding, and H.264 decoder carries out decoding to each frame video pictures wherein after code stream and show receiving.H.264 the frame type of code stream is divided into three kinds, I frame, P frame and B frame respectively, wherein I frame data can directly be decoded display in a decoder, and P frame data to rely on I frame data above could normal decoder, the front and back frame data that B frame data will rely in code stream could normal decoder.For the IP video that requirement of real-time is higher, its code stream is made up of I frame and P frame mostly, and the frame type as one section of H.264 its each frame of video code flow may be as follows: IPPPPPPPPPPPPIPPPPPPPPIPPPPPPP.Wherein the first frame must be I frame, and may be several P frame data below, and then is an I frame and multiple P frame, repeats with this.
Combination often needs out multi-channel video window show, wherein each road video likely can from different signal sources simultaneously, but also likely two-way wherein or multi-channel video from same signal source.For two video windows of signal source identical on combination, obtain a code stream in the inner meeting usually of combination processor to signal source for the consideration reducing the aspects such as offered load, and then by the multiple window displays of this part of code stream on combination.
For distributed processors, its each display unit may correspond to different display nodes, when opening first video window of certain signal source on combination video pictures normal all can be very fast decoding display because the first frame got from signal source can be all I frame; If but open the video window of an identical signal source again at other display units and this display unit there is no the video window of described signal source, then the display node of its correspondence of window newly opened will the code stream in Received signal strength source display of decoding.Because the code stream got from signal source when can not ensure new windowing is exactly just I frame, at this moment show node and just promptly can not carry out decoding display to the frame data got, the next I frame that by the time receive in code stream could start display.From the operating experience of user, this can directly cause first window holding each signal source to show very soon, and can show more slowly when holding video window again on different Node station.Its speed degree depends on I frame period.
Such as, combination has two display windows, A, B window is all from same signal source, and master server only obtains a code stream from signal source and is successively distributed to Node station decoding display corresponding to two windows according to order of windowing.
If first open window A, then window A will to decode display soon as first window of this signal source; Window A is kept to be in window display state, and open the another one window B of same signal source, now will get the code stream of this signal source from master server because of the display node that window B place display unit is corresponding, but the first two field picture received due to Node station when can not ensure that window B opens is I frame, therefore the next I frame always waited until in code stream arrives and just can start normal display by window B, therefore window and cause blank screen problem due to being non-I frame data of reception instantaneously, and window display speed is slow, and display effect is poor.
The current interface forced signal source when new windowing having technical scheme to propose to be provided by signal source exports the quick display that I frame ensures new windowing, the interface that the method needs equipment to provide extra, and when signal source does not provide corresponding interface, the program lost efficacy.
Summary of the invention
